[FIX] fields: inherit context_dependent from parent fields

If a field is inherited from another model, the attribute context_dependent
was not propagated correctly.

Example of bug:
>>> product = self.env['product.product'].search([], limit=1)
>>> product.name
'Whiteboard Pen'
>>> product.with_context(lang='fr_FR').name
'Whiteboard Pen'  # cache used
>>> template = product.product_tmpl_id
>>> template.name
'Whiteboard Pen'
>>> template.with_context(lang='fr_FR').name
'Marqueur pour Tableau Blanc'
>>> product._fields['name'].context_dependent
False
>>> template._fields['name'].context_dependent
True

Fixes odoo/odoo#33641
Closes odoo/odoo#33722
